Application filed September 30,1920. Serial N 0. 413,666.

To all'whom it may concern.

Be it known that I, HENRY N. MOORE, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Housing Coupling for Automobiles, of which the following is a. specification. v V

t In my reissue patent datedSept. 28, 1920,

N 0. 14,952, I have disclosed a. supplemental or auxiliary change speed mechanism between the difi'erential gearing and the usual two-speed transmission mechanism of a well known type of automobile, and in said patent I have provided a split coupling be- 'tween thehousing of the supplemental change speed mechanism and'thehousing of the drive shaft, said coupling fitting over the rear end of the drive shaft housing and behousing of the change speed mechanism. To assemble the transmission disclosed in said patent in place in the automobile, portions of the drive shaft housing and the drive shaft will be cut off so as to shorten them, and then the supplemental change speed mechanism will be coupledin position between the drive shaft and the, differential gearing. f

An object .ofthis invention isto make provision for coupling together the housing of the change speed mechanism and, the housing of the drive shaft differently than disclosed in the above mentioned patent.

. Another object of this invention is to secure a wedging clamp effect-upon the drive shaft housing.

' Another object is to effect clamping of the coupling by providing relative endwise 9 movement of two different members of the coupling. In someinstances bolts are relied upon to draw said members toward one another, and in other' instances nuts or screw-threaded sleevesare provided for this 4 purpose.

Another object oftheinvention isto pro. vide a rugged coupling and one which is easy to install.

i In Figure 1 is shown change speed mechanism housing A .and drive shaft housing B, between which is interposed a coupling C. On the shaft housing is mounted a leverD' for shifting an operating rod E which controls the change speed mechanism in thehousing A,

said change speed mechanism not being visible because of thenature of theview. The foregoing described elements, with the ex- 7 detail in the above and are only illustrated general herein in order to the invention assembled in'place in the automobile. f In Figure 1 the character to d have been described in mentioned patent and described 111 C is employed esignate any suitable type of coupling it is analogous lto-t-hat shown in. detail in Figs.- 2 and 3.

The con ling shown'in Figs. 2 and 3 is constructe as follows: There is provided a chambered coupling member." 1 having flangesQ and ears 3, the flange 2 being for securing at one end to a housing and constructed at said end to hold a bearing for a shaft, the other end of the tubular member forming a sleeve, a slotted wedge shape jaw-contracting member in the sleeve having its inner face aslant outwardly to- Ward the bearing, a ring-shape slotted jaw member extending through the jaw-contracting member and having a slanting outer face complementary to the slanting face of the jaw-contracting member, and means to force the jaw-contracting member to- 1jjvard the bearing to contract the jaw mem- 2. A coupling of the character described comprising a tubular member constructed for securing at one end to a housing and constructed at said end to hold a bearing for a shaft, the other end of the tubular member forming a sleeve, a slotted wedge shape jaw-contracting member in the sleeve having its inner face aslant outwardly toward the bearing, a member extending through the jaw-contracting member and having a slantingouter face complementary to the slanting face of the jaw-contracting member, the jaw member having screw-threads, and a nut engaging the screw threads and bearing against one end of the her to contract the jaw member.
